In brief
VDI 5200 Part 1 is a German engineering guideline that structures factory planning projects into seven sequential phases: setting of objectives, establishment of the project basis, concept planning, detail planning, preparation for realization, realization monitoring and ramp-up support. It applies to new planning, replanning, extension, dismantling and revitalization, and to every level of consideration — from a single workstation to a production network.
What the guideline is for
Factory planning projects rarely fail on the arithmetic. They fail because layouts get drawn before the objectives are settled, or because decisions are made before the data is sound. VDI 5200 Part 1 answers that with a sequence: each phase produces the result the next one needs as input.
The practical value lies less in completeness than in reviewability. Because each phase has a defined deliverable, there is a natural decision point at the end of it — continue, or rework. And because the phases carry agreed names, client, planner, architect and suppliers end up describing the same thing with the same words. In projects with international teams this is often the larger benefit of the two.
What triggers a factory planning project. Internally: a new production strategy, a changed product portfolio, capacity constraints. Externally: shifting markets, new legal requirements, changes in the supply chain.
Planning cases covered by the guideline:
- New planning — building a factory on a greenfield site
- Replanning — reorganizing an existing factory
- Extension — increasing capacity or floor space
- Dismantling — reducing or shutting down areas
- Revitalization — returning existing assets to use, or repurposing them
Levels of consideration: workstation, segment, building, site, network. The phase logic stays the same; the level of detail changes.
Objectives against which a factory planning project is measured: greater flexibility and adaptability, higher product quality, better economic efficiency, attractive workplaces.
About the guideline itself
The Verein Deutscher Ingenieure (VDI, the Association of German Engineers) issues technical guidelines that function as recognized rules of engineering practice in Germany. They are not law and not certifiable standards. A VDI guideline becomes binding only when the parties agree to it in the planning contract — which happens often in factory planning, precisely because the phase structure makes scope and acceptance easy to define.
Part 1 of the series was published in Berlin in 2011 by the VDI Society for Production and Logistics under the German title Fabrikplanung — Planungsvorgehen, which translates as "Factory planning — Planning procedure". It is the part referred to whenever a project speaks of "planning to VDI 5200".
How it relates to international practice. There is no direct ISO or EN equivalent covering the factory planning process end to end. Projects outside Germany typically arrive at a comparable structure through their own stage-gate or front-end-loading models. The value of adopting VDI 5200 in an international project is usually not that it is better, but that it is written down: it gives a mixed team of German and non-German engineering partners a shared vocabulary that already exists in both languages.

The seven phases
Phase 1 — Setting of objectives
The starting point is not the site but the corporate strategy. Product and sales strategy together define the strategic direction, the planned products, the possible locations, and the budget and time frame. From there, the factory objectives are derived: production quantity per product, depth of added value, candidate regions and plots, schedule and cost envelope.
The third step establishes the evaluation criteria against which the later concepts will be measured. Which criteria make sense depends on how sharply the objectives could be stated. Where production volumes and product mix are only vaguely defined, flexibility and adaptability move to the front. The more concrete the objectives, the more weight profitability and efficiency carry. Innovation potential and implementation risk are common additional criteria.
Finally, work packages are derived and structured. Given the long time horizon of a factory planning project, the rule is: as specific as necessary and as open as possible. Concretely worded work packages help everyone involved do the work; an overly narrow solution space makes it impossible to respond to change. Planning several scenarios within two deliberately chosen extreme cases has proven useful.
Phase deliverable: documented factory objectives, evaluation criteria, structured work packages.
Phase 2 — Establishment of the project basis
This phase builds the data foundation. All planning-relevant data and processes are recorded on site together with the project team. Data acquisition follows a checklist agreed between planner and client; the collected data — quantities, areas, orders, inventories — is processed into a consistent planning database. Every later analysis, evaluation and calculation rests on it. Errors introduced here travel through every subsequent phase.
In parallel, the actual processes are recorded using the value stream method. Main processes and workflows are captured through walkthroughs, observation and interviews with the responsible specialists — from incoming goods to dispatch, supplemented by data on frequencies and specific customer requirements. The aim is a sound understanding of how the plant works today, what it produces, and what equipment it runs.
Process mapping and data analysis together reveal the weaknesses. The focus is on space utilization, material flow relationships, transport effort, capacity constraints and technology options. For each identified weakness, target processes are defined; they form the basis of the concepts in phase 3. Data, processes, premises and project assumptions are validated with the client and formally adopted.
Phase deliverable: validated planning database, documented actual processes, assessed weaknesses, defined target processes.
Phase 3 — Concept planning
Phase 3 develops several scenarios. The factory is first structured — segmented by process, product or technology, for instance to separate slow-moving exotics from fast movers so that flows are not interrupted.
Dimensioning then calculates machine, logistics and indirect areas from the data and area analyses of phase 2, incorporating the target processes and the volume forecasts from phase 1 with their resulting space requirements.
Ideal planning produces the ideal layout: the optimal arrangement of production and logistics areas relative to one another, based on the calculated areas and deliberately detached from the current layout. The point is not to build the ideal layout — it is the yardstick against which the feasible variants are measured. The work is done with "verified blocks": the ideal layout is drawn as a block layout whose blocks are re-checked in detail planning for both area and geometry, so that not only the size but also the shape of each area holds up.
From the ideal layout, real planning develops the plant structure variants with restrictions applied. Carrying the evaluation criteria and factory objectives along from the start avoids effort spent on variants that will not survive the assessment anyway.
Phase deliverable: segmentation, dimensioned areas, ideal layout, assessed plant structure variants.
Phase 4 — Detail planning
Fine planning converts the best-rated variant into a complete CAD layout, 2D or 3D, down to workstation level. It covers operating resources, staging zones, handling areas, tugger train stops, traffic routes, buffer zones and expansion areas. Structural restrictions — hall dimensions, column grids, floor loads, fire protection zones, expansion joints — are entered and checked.
The logistics concept describes, for every line, machine, workstation and storage location, the processes and equipment for transport, provision and storage from incoming to outgoing goods. Transport and storage throughput is derived from the production programme and the material flow relationships, the flows are integrated into the model, and the resulting flow intensities drive the selection of transport equipment and the dimensioning of delivery, buffer, transfer and disposal areas. Transport concepts — tugger train systems, for example — are compared on investment, operating cost, flexibility, security of supply and space consumption.
For approval, layout plots, construction drawings and building description are submitted to the responsible building authority. For the equipment and trades to be procured, specifications and tender documents are prepared.
Phase deliverable: verified detail layout, logistics concept, approval documents, specifications.
Phase 5 — Preparation for realization
On the basis of the specifications, the request for quotation goes out: identifying suitable suppliers, running the tender, checking incoming bids against the specification for completeness and — at least as importantly — against each other for comparability. Without comparable bids there is no sound award decision.
Once the bids are in, the business case determines the profitability of the plant structure variants including their logistics solutions. A rough estimate can already serve as a criterion in phase 3, but it only becomes reliable with quotations in hand. P&L and ROI calculations are the common methods. The award goes to the economically best offers overall, not the cheapest.
Implementation planning produces a roadmap from investment approval through tendering and procurement to commissioning, including relocations and workstation installations. Activities and resources are scheduled and verified with the client's own experts, and dependencies between implementation steps are made visible. One item that is regularly underestimated: lead time for building up buffer stock, so that the plant stays able to deliver during the move. Continuous monitoring of progress follows.
Phase deliverable: comparable bids, sound business case, award decision, approved implementation roadmap.
Phase 6 — Realization monitoring
The execution plans produced by the supplier are checked continuously, as are equipment installation, trades and construction progress. Compliance with the approval and the performance specification has to be verified on an ongoing basis, including updating the schedule and documenting the contractor's construction sequence.
Cost control compares invoices against order totals. In parallel, the documentation is compiled systematically — drawings as well as calculated results — together with the list of defect claims and the monitoring of their rectification. All planning data is handed over electronically to the project team.
Acceptance of equipment and machinery covers installation, alignment and anchoring on site, instruction of operating personnel, and geometry protocols verifying machine accuracy. It splits into preliminary acceptance at the supplier's plant and final acceptance at the customer's plant, carried out under production conditions on components defined in advance. Process capability, machine capability and technical availability of the overall system must all be demonstrated.
Phase deliverable: accepted construction work and equipment, complete documentation, cost verification.
Phase 7 — Ramp-up support
Start of production (SOP) marks the beginning of commercial production. The phase ends when the targets set for product and process quality, output volume, capacity utilization and manufacturing cost have been met.
During production start-up, production parameters are increased in a controlled way — beginning with high-volume reference products and working through to slow movers. The ramp-up largely determines the return on the whole project: if time to market slips against plan, revenue is deferred, the payback period lengthens, and in the worst case market share is lost. A successful ramp-up depends on the stability of ongoing operations — not only in production, but in logistics, quality assurance and maintenance as well.
The closing evaluation checks whether the factory objectives defined in phase 1 were achieved and records lessons learned. Project completion includes handing over all documents and documentation from the project partners to the client.
Phase deliverable: achieved target parameters, documented evaluation, complete handover.
How VDI 5200 relates to other frameworks
VDI 5200, the HOAI and VDI 2870 are regularly confused or played off against one another. They describe different things and do not exclude each other.
| VDI 5200 Part 1 | HOAI, service phases 1–9 | VDI 2870 | |
|---|---|---|---|
| Subject | The factory planning procedure | German fee structure for architects and engineers | Holistic production systems |
| Perspective | Production, material and information flow | The building and its technical services | Methods for shaping processes in operation |
| Status | Recognized rule of practice, adopted by contract | Statutory instrument governing fees | Recognized rule of practice |
| Structure | 7 phases | 9 service phases | Fundamentals and method catalogue |
| Question it answers | How must the factory work? | How is the building planned and remunerated? | Which methods are used to improve? |
The practical relationship. VDI 5200 answers what should be built — structure, areas, material flow, layout. The HOAI service phases govern how the building is planned and how that planning work is paid for. The two run in parallel with an offset: concept planning under VDI 5200 (phase 3) produces the input that preliminary design under HOAI (service phase 2) needs in order to be meaningful at all. Reversing the order — starting with the building — means planning production into an envelope that was never shaped for it. This holds regardless of jurisdiction; the HOAI is simply the German name for the second half of the pair.
VDI 2870 starts later. It describes methods for operating a factory, not for planning one. The touchpoints are in phase 2, where value stream mapping comes from that tradition, and in phase 7, where stable operation has to be secured.
